The UF504 is an industry-standard part number for an ignition coil used in many Chrysler, Dodge, Jeep, and Ram vehicles equipped with V8 HEMI engines (5.7L, 6.1L, 6.2L, and 6.4L). It is not a Mopar brand-exclusive part number, but rather the aftermarket designation often used for Mopar-compatible replacements
An ignition coil serves as a heavy-duty transformer. It converts the vehicle's low 12-volt battery power into the massive 25,000 to 47,000 volts required by the spark plugs. This high-voltage spark is essential to ignite the air-fuel mixture in your engine's cylinders.
- Engine misfires: Rough idling or hesitation when accelerating.
- Decreased power and poor fuel economy: The engine works harder to run, using more gas.
- Check Engine Light: The dashboard light will illuminate, and diagnostic scanners will often throw cylinder misfire codes
